Oceanography and Marine Biology
Increasing interest in marine biology and its relevance to environmental issues creates a demand for authoritative reviews of recent research. Oceanography and Marine Biology has addressed this demand for nearly 40 years. This annual review considers basics of marine research, special topics, and emerging new areas. Regarding the marine sciences as a unified field, the text features contributors who are actively engaged in biological, chemical, geological, and physical aspects of marine science. This edition includes a full color insert and covers such topics as the ecological status of the Great Barrier Reef, the effects of coral bleaching on fisheries, and the biology of octopus larvae.

Advances in aquaculture hatchery technology
This chapter deals with the different methods used in the world to produce hatchery-reared juveniles of Octopus vulgaris, including capture and transport methods, broodstock conditioning and paralarval rearing technology. First, a review is made of the different systems used for hatchery production of the various Cephalopod species in which there is the greatest commercial interest. Then, specifically for Octopus vulgaris, conclusions and standardized methods related to the spawning process, the control of embryonic development and, finally, a protocol for paralarval rearing are also given. The main bottlenecks and future research trends are pointed out, and important sources of further information and advice are referenced. A brief review of the state-of-the-art on larvae and juvenile rearing of other cephalopods species is also included in this chapter.

The Digestive Tract of Cephalopods: at the Interface Between Physiology and Ecology
Aristotle in the Historia animalium, (Book IV) gives one of the earliest descriptions of the anatomy of the cephalopod digestive tract, comparing it to that of other molluscs. From dissections of cuttlefish several key features of the cephalopod digestive tract were described: the beak (“teeth”) and radula (“tongue”), the passage of the oesophagus through the brain en route to the crop and stomach. The stomach is described as having spiral convolutions like a trumpet snail shell suggesting that the structure described is actually the caecum. The gut then turns anteriorly so that the anal opening is near the funnel leading a modern author to comment that they “defaecate on their hea...
Advances in Aquaculture Hatchery Technology
Aquaculture is the fastest-growing food production sector in the world. With demand for seafood increasing at astonishing rates, the optimization of production methods is vital. One of the primary restrictions to continued growth is the supply of juveniles from hatcheries. Addressing these constraints, Advances in aquaculture hatchery technology provides a comprehensive, systematic guide to the use of current and emerging technologies in enhancing hatchery production.Part one reviews reproduction and larval rearing. Aquaculture hatchery water supply and treatment systems, principles of finfish broodstock management, genome preservation, and varied aspects of nutrition and feeding are discuss...
